Answer:
Explanation: Hydropower is the generation of electricity from water through the construction of dams. it is a renewable energy source use over a wide range of environment. Construction of a waters storage project can raise the water level behind a dam from a few feet to several hundred feet by prevention water free flow called Inundation.
It leads to migration of human and other living organism such as fish and salmon. Salmon movement may be disoriented through the slower move of the water this leads to migration.
Fish moving around the dam coming in contact with turbines and the walls of the dam can become stressed, injured or die
vegetation and surrounding water it provide habitat for birds, waterfowl, and small and large mammals when hydroelectric project results in blockage of free-flowing river, the nesting, forage, and cover provided for the organism in these areas is temporarily or permanently lost.
Apples are drawn to a massive object, like the earth, and fall down under a gravitational constant. On the other hand, planets revolve around a more massive object under the same premise. It’s the same idea, just one follows a linear path, and the other has a uniform circular motion path because other forces are acting on it. In other words, the planets ARE still falling, but the sun is also pulled by them so they just keep dancing.
Oxygen has a partial negative charge, whereas hydrogen had a partial positive charge.
This means that water molecules are polar and can be used to dissolve a lot of chemicals, that's why water is such a popular solvent.
The example that does not exhibit sexual selection is:
D. male elephant seals fighting over territory and potential female mates
The competition for territory is also one that helps the elephant seals survive. This is because a seal with a larger territory is likely to have access to a greater amount of resources, ensuring its survival.
